  It makes no difference whether it is enabled or not.

  This actually worked. For mplayer. It spit out the same error message
but then tried ALSA and had success.
  Still, the original problem can sometimes block another sound source
like Flash player in a browser. I have found no definable pattern to when
or not sound will work. Usually right after a boot but not always.
Sometimes just waiting a while allows whatever to let go of the sound
channel. Other times what worked before goes silent.
  Using "speaker-test" always works. But then it seems to create the
blocked sound problem preventing some other programs from making noise.
